Hi everybody,
My problem is about the operator "sqrt".
In old version such as reduce 3.6 or 3.7, sqrt(x^22*x+1) gives the
result abs(x1) correctly, but now it turns out to be x1, no matter I
turn the switch PRECISE on or off.
If I replace the expression in sqrt into "x^2", it gives "abs(x)"
correctly.
Reduce (Free PSL version), 12Nov2009 ...
1: sqrt(x^22*x+1);
x  1
2: sqrt(x^2);
abs(x)
Does anyone know how to make the operator work properly in current open
source
version like in reduce 3.7? I am using a psl build of open source
version.
Looking forward to your reply.
Best regards,
Twain
